Abstract
An excitation winding arrangement is provided for low-speed synchronous machines wherein the poles are configured without pole shoes and accommodate the excitation windings. The excitation winding arrangement includes coils of flat conductors which define the excitation windings. The flat conductors are wound so that their surfaces are parallel to the walls of the poles and the coils form a self-supporting component which can be improved by hardened turn insulation. These coils are secured only at the end-faces of the poles by a mounting arrangement. Effective cooling of the coils in the pole gap is thereby achieved.
